It is widely used for the partitioning and decoration of various interior spaces such as living rooms, bedrooms, and studies.
[0003] Existing methods for surface treatment of concealed grille doors typically involve placing the door panel on a grinding machine and using the grinding wheels on the machine to treat the surface. Then, the grille strips are placed on another machine for grinding. However, current equipment can only treat either the door panel or the grille strips, making it difficult to use one machine for both. It requires separate operations, which is cumbersome, increases processing costs, occupies space, affects processing efficiency, and is very inconvenient to use.
[0004] Therefore, it is necessary to design a surface treatment device for concealed doors that can polish the surface of door panels and the top and sides of the grille strips, achieving dual functionality, reducing processing costs, improving processing efficiency, and being easy to use.

Detailed Implementation
[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.
[0022] A surface treatment device for a concealed door, such as Figures 1-5 As shown, it includes a grinding table 1, a grinding machine 5, a guide frame 13, a moving component, a fixing component, and a grinding component. The grinding table 1 has a moving component at the front, and the grinding machine 5 is mounted on the moving component. The guide frame 13 is connected to the upper rear side of the grinding table 1. The grinding table 1 has a fixing component on the right side for fixing the grid hidden door or grid strips. The grinding table 1 has a grinding component for grinding the sides of the grid strips.
[0023] like Figure 1 and Figure 2 As shown, the moving component includes a first motor 2, a first lead screw 3, and a first connecting block 4. The first motor 2 is connected to the front right side of the grinding table 1. The first motor 2 and the processor are electrically connected through a control module. The first lead screw 3 is connected to the output shaft of the first motor 2. A fixing component is provided on the upper left front side of the grinding table 1. The first lead screw 3 is rotatably connected to the fixing component. The first connecting block 4 is threadedly connected to the first lead screw 3. The first connecting block 4 is also slidably connected to the guide frame 13. The first connecting block 4 is connected to the grinding machine 5.
[0024] like Figure 1 and Figure 3 As shown, the fixing component includes an electric push rod 6 and a fixing block 7. The electric push rod 6 is connected to the upper right side of the grinding table 1. The electric push rod 6 and the processor are electrically connected through the control module. The fixing block 7 is connected to the telescopic end of the electric push rod 6. The fixing block 7 is E-shaped for easy fixing.
[0025] like Figure 4 and Figure 5 As shown, the grinding assembly includes a second motor 8, a second lead screw 9, a second connecting block 10, a grinding motor 11, grinding wheels 12, and a connecting shaft 14. The second motor 8 is connected to the inner side of the right front part of the grinding table 1. The second motor 8 and the processor are electrically connected through a control module. The output shaft of the second motor 8 is connected to the second lead screw 9, which is rotatably connected to the left front part of the grinding table 1. The second lead screw 9 is threadedly connected to the second connecting block 10, which is slidably connected to the grinding table 1. The grinding motor 11 is connected to the second connecting block 10, which is electrically connected to the processor through a control module. The output shaft of the grinding motor 11 is connected to the connecting shaft 14, which is rotatably and slidably connected to the grinding table 1. Six grinding wheels 12 are connected to the connecting shaft 14. The grinding wheels 12 are made of alumina and have good wear resistance and thermal stability.
[0026] When the surface of the concealed door needs to be treated, this device can be used. The grinding table 1 contacts the tabletop or ground, and the door panel is then placed on the grinding table 1. The processor then activates the electric push rod 6 via the control module. The electric push rod 6 moves the fixing block 7 (E-shaped) to contact and fix the door panel. Next, the first motor 2 is activated, driving the first lead screw 3 to rotate along the fixing component. Under the action of the thread, the corresponding first connecting block 4 moves, causing the grinding machine 5 to move. This causes another first connecting block 4 to move along the guide frame 13. Simultaneously, the grinding machine 5 operates to polish the door panel. The surface is polished, and then the first motor 2 operates in reverse, causing the first lead screw 3 to rotate in reverse. Under the action of the thread, the corresponding first connecting block 4 moves in reverse, driving the polishing machine 5 to move in reverse for polishing. This causes the other first connecting block 4 to move in reverse and reset. Then, the polishing machine 5 moves back and forth to polish the surface of the door panel. The guide frame 13 is I-shaped. After polishing, the electric push rod 6 operates in reverse, causing the fixing block 7 to move and reset and disengage from the door panel. Then, the door panel is flipped over, and the above operation is repeated to clamp and polish the door panel. After polishing, the polishing machine 5 is turned off, and the door panel is removed.
[0027] When it is necessary to polish the grille strips, place the grille strips on the polishing table 1. Then, the electric actuator 6 drives the fixing block 7 to move and fix multiple grille strips in contact, thereby fixing the door panel or grille strips during polishing, preventing displacement of the door panel or grille strips, and improving polishing stability and quality. Then, repeat the above operation, and the polishing machine 5 moves back and forth to polish the upper side of the grille strips. After the upper side is polished, turn off the first motor 2 and start the second motor 8. The second motor 8 drives the second lead screw 9 to rotate, and the second connecting block 10 moves under the action of the thread, which drives the polishing motor 11, the polishing wheel 12 and the connecting shaft 14 to move. At the same time, the polishing motor 11 is started, and the polishing motor 11 drives the connecting shaft 14 to rotate, so that the polishing wheel 12 rotates to polish both sides of the grille strips. The polishing wheel 12 is made of alumina. The second motor 8 and the grinding motor 11 operate in opposite directions, causing the second lead screw 9 to rotate in the opposite direction. Under the action of the thread, the second connecting block 10 moves in the opposite direction, driving the grinding motor 11, the grinding wheel 12, and the connecting shaft 14 to move in the opposite direction. At the same time, the reverse rotation of the connecting shaft 14 drives the grinding wheel 12 to rotate in the opposite direction for grinding. Then, the grinding wheel 12 reciprocates and rotates to grind both sides of the grid strip, thus grinding the surface of the door panel and grinding the top and sides of the grid strip. This achieves two uses in one machine, reducing processing costs, improving processing efficiency, and making it convenient to use. After grinding is completed, the second motor 8 and the grinding motor 11 are turned off, and the fixing block 7 is disengaged from the grid strip. Then, the above operation is repeated to continue processing the door panel or grid strip. Finally, the ground door panel and grid strip are assembled to form a grid hidden door.
[0028] The control method in this embodiment is controlled by a controller. The controller circuit can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this document is mainly used to protect mechanical devices, and the control method and circuit connection will not be explained in detail here.
[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
